    DRAFT VEGETATION COMMUNITIES OF SAN DIEGO COUNTY Based on “Preliminary Descriptions of the Terrestrial Natural Communities of California” prepared by Robert F. Holland, Ph.D. for State of California, The Resources Agency, Department of Fish and Game (October 1986) Codes revised by Thomas Oberbauer (February 1996) Revised and expanded by Meghan Kelly (August 2006) Further revised and reorganized by Jeremy Buegge (March 2008) March 2008 Suggested citation: Oberbauer, Thomas, Meghan Kelly, and Jeremy Buegge. March 2008. Draft Vegetation Communities of San Diego County. Based on “Preliminary Descriptions of the Terrestrial Natural Communities of California”, Robert F. Holland, Ph.D., October 1986. March 2008 Draft Vegetation Communities of San Diego County Introduction San Diego’s vegetation communities owe their diversity to the wide range of soil and climatic conditions found in the County. The County encompasses desert, mountainous and coastal conditions over a wide range of elevation, precipitation and temperature changes. These conditions provide niches for endemic species and a wide range of vegetation communities. San Diego County is home to over 200 plant and animal species that are federally listed as rare, endangered, or threatened. The preservation of this diversity of species and habitats is important for the health of ecosystem functions, and their economic and intrinsic values. In order to effectively classify the wide variety of vegetation communities found here, the framework developed by Robert Holland in 1986 has been added to and customized for San Diego County. To supplement the original Holland Code, additions were made by Thomas Oberbauer in 1996 to account for unique habitats found in San Diego and to account for artificial habitat features (i.e., 10,000 series).

The species also occurs in the foothills of the Sierra Nevada from El Dorado County to Madera County and on South Farallon, Santa Catalina, Los Coronados, and Ano Nuevo islands off the coast of California (Petranka 1998, Stebbins 1951, Stebbins 1985). Arboreal salamander occurs from sea level to an elevation of about 5,000 feet (1,520 meters) (Stebbins 1985). Distribution in the Planning Area Arboreal salamander reportedly occurs in the foothills and lower elevations of every mountain range on National Forest System lands, although it is seldom seen (Stephenson and Calcarone 1999). There are records of occurrence for this species on the Los Padres National Forest near upper San Juan Creek and on the Cleveland National Forest near Soldier Creek (USDA Forest Service file information), San Gabriel foothills east to Day Canyon, and in the San Jacinto Mountains (Goodward pers. comm.). Systematics There are four species in the genus Aneides in the western United States, three of which occur in California (Stebbins 1985). Of these three, only arboreal salamander ranges into southern California. Most of the Aneides salamanders climb (Stebbins 1985). Arboreal salamander consists of two chromosomally differentiated groups that intergrade in south and east-central Mendocino County, about 56 miles (90 kilometers) north of the San Francisco Bay region (Sessions and Kezer 1987).

Oberbauer County of San Diego Department of Planning and Land Use, 5201 Ruffin Road, Suite B, San Diego, CA 92123, U.S.A.; [email protected] ABSTRACT.—Scarabaeoid beetles are diverse in San Diego County, California, with 8 families, 53 genera, and approximately 50 species repre- sented. Vegetation communities in the county are likewise diverse and directly responsible for supporting the diversity of scarab beetles. Part I of the Scarabaeoid Beetles of San Diego County, California presents data on 8 species in the following 7 families: Glaresidae (), Trogidae (4), Pleocomidae (2), Geotrupidae (5), Ochodaeidae (3), Hybosoridae (), and Glaphyridae (2). This group of diverse beetles is adapted to a wide variety of terrestrial habitats where they feed upon hair, feathers, carrion, other decomposing organic matter, and plants.

  • White-Headed Woodpecker
    Woodpeckers — Family Picidae 329 White-headed Woodpecker Picoides albolarvatus In San Diego County, which represents the south- ern tip of its range, the White-headed Woodpecker is uncommon to rare, breeding only in coniferous forest near the mountain tops. Even here it occu- pies only a fraction of the habitat, occurring mainly where the sugar pine is an important constituent of the forest. Only twice have vagrants been recorded in San Diego County away from the mountains.
